Abstract: A rolling bearing cage includes axially spaced side rings, cage webs connecting the side rings, cage pockets, and first and second cage ends. The cage webs have rolling element guides projecting radially inwards and the cage pockets are formed between the rolling element guides. The first cage end has a closing element formed by an axial groove at a radial web surface of a cage web that is reinforced relative to the other cage webs and delimits a penultimate cage pocket. The second cage end has a closing element formed by a partial cage web connecting the end portions at the second cage end to one another. The partial cage web is arranged to hook into the axial groove to form a cage lock that secures the second cage end to the first cage end against unintentional loosening in a peripheral direction and in both radial directions.

Abstract: A plastic cage consists of two side rings that have a common axis of rotation and are axially spaced apart from one another, and a plurality of cage webs that connect the side rings to one another and between which pockets are formed for receiving rolling elements, wherein the plastic cage is axially slotted at at least one peripheral location by a parting line which defines a first cage end and a second cage end and at the boundary surfaces of which mutually corresponding closure elements are located, by means of which the first and second cage ends can be fixed relative to one another both in the axial and radial direction and in the peripheral direction.

Abstract: The invention relates to an inner-ring-fastened roller sleeve (1), comprising: —an inner ring (2), which is fastened on a shaft or axle; and—a roller-and-cage assembly (3), which is disposed on said inner ring (2) and is formed by a bearing cage (4), which consists of two side rings (5, 6) and a plurality of connecting webs (7), and by a plurality of roller-type rolling elements (8) inserted into said bearing cage (4), which roller-type rolling elements are retained by the bearing cage (4) at regular spacings in the circumferential direction and roll on an inner raceway (9) formed by the outer lateral surface of the inner ring (2), wherein the roller-and-cage assembly (3) is axially guided by means of two flanges (10, 11), which are provided on the axial sides of the inner ring (2) and extend radially outward.
